Under the new situation,traditional high energy-consuming industries are facing the problem of overcapacity, and it is urgent to upgrade the industrial structure through collaborative innovation networks.Based on technological innovation mechanism, innovation environment mechanism and innovation management mechanism,builds up structural model and evaluation index system of collaborative innovation networks operation mechanism in energy intensive industries,and use the synergetic degree model to analyze its collaborative process.Through an empirical study of the operation mechanism of collaborative innovation networks in energy intensive industries from 2008 to 2016 in Shenhua enterprise,the article made conclusions that the three mechanisms influence each other and promote each other, promote the innovative ability of collaborative innovation networks in energy intensive industries by synergy.
